That's impossible to answer at the moment, the scale of the Milky Way is too vast to give a clear indication.
However, from estimates, there is a good change that at least 50% of all stars will have some sort of planetary system.

More complete answer: It's beginning to look as if planets and planetary systems may be the norm rather than the exception. There are 300+ "extra-solar" planets, and more being discovered each month, and with a variety of new tools becoming available to detect signs of planets.

Which galaxy are the planets on?
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
What are the planets in the galaxy M51?
We can't even see individual STARS in other galaxies, much less PLANETS. We have no idea how many stars are there.
Where do Stars Galaxies Nebulae and Planets fit in the grand scheme?
Galaxies/nebulae are at the top of the tree; each one contains several billion stars. Each star might have many planets orbiting around it, and planets can have many moons.
What are some moons names in the milky way galaxy?
Because we only know the names of the planets in our Solar System, the right question could have been "What are the planets in our solar system?" which is of course very elementary. Some people can sometimes get confused between solar system and galaxy
What is a group of planets and their moons that orbit a central star?
A group of planets moving around a star is called a solar system. Planets outside our solar system are called exoplanets. Despite the difficulty of detection, many hundreds have been discovered recently, orbiting other stars.
How many moons Andromeda galaxy have?
It is not known. The Andromeda Galaxy contains about a trillion stars, many of which certainly have planets, though we don't know how many. Many of the planets likely have moons. All told, there are likely several hundred billion to several trillion moons in the Andromeda Galaxy.
How many planets and moons are in the Star Wars galaxy?
There are billions of planets and moons in the Star Wars galaxy.
How many moons altogether are there in your galaxy?
My galaxy, the Milky Way (which is also your galaxy; I am sure that the person asking this question is not a visitor from another galaxy) has not been examined in enough detail to say even how many planets it contains, much less how many moons orbit those planets. But given that our own solar system has numerous moons, and there are billions of other stars in the galaxy which probably also have planets and moons, at a wild guess I could estimate possibly a hundred billion moons.
Is solar system a galaxy?
No. A galaxy is a collection of stars ... possibly as many as hundreds of billions of stars in one galaxy. Our sun ... including all of the comets, asteroids, moons, and planets including earth that make up the solar system ... is one star out of the estimated 200 to 400 billion stars in our galaxy.
Which galaxy are the planets on?
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
Are the stars in the sky different planets and moons we have not discovered yet?
No. We know what the stars are. They are not planets. They are distant suns, many of which do have undiscovered planets.
How many moons and stars are there in the milky way?
There are about 100 billion stars in the Milky Way Galaxy. We only know of moons in the solar system - 169 of them.
Why do stars planets and moons do not collide it self?
The moon is many times closer to the Earth than the stars are.
How many moons does the milky galaxy have?
We only know about the number of moons for our own solar system. Technology now lets us see very large planets around other nearby stars. We have found a few near Earth size. However currently we can not detect moons around planets in other solar systems.
How to calculate the number of solar systems in our galaxy?
The number of stars in our galaxy is a few hundred billion. You probably refer to the number of stars that have planets; it is known that many stars in our neighborhood have planets, but it is yet too early to give even an approximate percentage. It is possible that most stars have planets, but this can't be stated for sure, from the available data.The number of stars in our galaxy is a few hundred billion.

How are moons and planets alike?
Most but not all larger MOONS (bodies that orbit planets, moons, or asteroids) accreted in the same way that PLANETS did, assuming a variable density and a nearly spherical shape. Very large moons such as Titan have many of the characteristics of planets: vulcanism, atmospheres, and weather. Generally speaking, moons orbit planets in the same way that planets orbit stars.
